The cultural origin and background of cast copper sculpture techniques and bronze forging art are the main branches of sculpture art. On the basis of inheriting the traditional copper art elements and fabrication skills, the cast copper sculpture in the present world absorbed more and more artistic element by combining modern arts and taste. Through continuous innovation in technology, it has undergone fundamental changes in artistic concept, theme and art form, and has become the main spiritual and civilized life of the people.
Now urban metal sculptures are hidden in shady paths, or dotted in squares, busy streets, or scattered in parks, public spaces and others. These art works beautify the city while enriching the spiritual and cultural life of citizens.
Cast copper sculptures feature long history in China, often used in the fabrication and production of fine sculptures, but the cast copper sculpture oxidizes and corrodes easily, so we must pay attention to daily maintenance and regularly clean the cast copper sculpture, gently wipe the surface with a clean, dry, soft cotton cloth. It is best to brush some places with trenches or use muslin wipe to achieve the polishing effect.
There are small imperfections or holes on the copper carving after long time display, which need to be repaired in time to prevent the expansion of the area. It can be fixed with epoxy resin and copper powder mixed and glued to the copper carving. As an adhesive, epoxy resin has a strong adhesive force. For those copper sculptures whose surfaces have been mineralized, the only way to make the relics solid is to maximize the overall shape and stabilize the deteriorated oxides, carbonates and other salts of the metal. The filling material can be a fiberglass fabric impregnated with a colored epoxy or polyester resin for overall reinforcement.
Furthermore, the environment should be kept dry and free of pollutants. The room temperature is best controlled between 18°C and 24°C. When we maintain the cast copper sculpture, we should avoid the erosion of external chemicals, such as acid, alkali and chloride. Proper maintenance will surely last the display period.
